Comment On: Serum Vitamin D3 Levels And Diffuse Hair Fall Among The Student Population In South India: A Case-Control Study

The study by Nayak et al. investigated the relationship between serum Vitamin D3 levels and diffuse hair fall among students in South India. It found a significant perception among participants that dietary factors contributed to hair fall, though details on diet were not collected. Despite recording sunlight exposure duration, the time of day was not considered, leading to statistically insignificant differences between groups. Only one patient had normal Vitamin D3 levels, highlighting widespread hypovitaminosis D. The study suggested that Vitamin D supplementation might become a routine treatment for diffuse hair fall.
